Thanks for the reply. I need to add something like this, right? #Reject stuff for netvisao smtp server REJECT loc net:213.228.128.64 tcp 25 Cheers, Paulo Matos On Wed, 2004-03-31 at 01:20, Tom Eastep wrote:> Paulo Jorge de Oliveira Cantante de Matos wrote: > > > How can I block my LAN users to access "mail.netvisao.pt", my ISPs POP3 > > server? > > > Add the appropriate REJECT rule. http://shorewall.net/ports.htm should help. > Be sure to read the notes immediately below the index. > > -Tom-- Paulo J.

Indeed, I''m sorry, my error. Blocking netvisao.pt smtp server was my initial goal.
